چکیده انگلیسی
Utilizing a single-stage light gas gun the plane shock-wave experiments were performed in order to determine the dynamic behavior of the remolded loess whose density was 1.8â¯g/cm3 and saturation degree was 22% at stress levels between 0.2 and 1.6â¯GPa. Wave motions were detected by four electromagnetic particle velocity sensors embedded into the samples directly. The typical waveforms of particle velocity and the Hugoniot data of the experiments were presented in this paper. The dynamic stress-strain relation that was critical in researching the shock propagation in the sample could be obtained when the Lagrangian analysis method was utilized to the four particle velocity waveforms. Shock speed versus particle velocity was linear correlation. The speed of follow rarefaction wave was several times the speed of loading shock wave, corresponding, the unloading modulus was greater than the loading modulus, and the hysteresis effect was exhibited in the dynamic stress-strain relation.
